Answer:
Experiment plays many roles in science. One of its important roles is to test theories and to provide the basis for scientific knowledge. It can also call for a new theory, either by showing that an accepted theory is incorrect, or by exhibiting a new phenomenon that is in need of explanation.
Explanation:
Answer:
<em><u>= 0.1 M </u></em>
Explanation:
450mL = 0.45L
If 24g of a solute are weighed by 1 mole of solute
1.2g of a solute will be weighed by ( 1.2 ÷ 24 )
=<u> 0.05 moles of a solute.</u>
0.45L of a solution are occupied by 0.05 moles
1L will be occupied by ( 1÷0.45 ) × 0.05
= 0.1 M
Answer:
The correct answer is option 3.
Explanation:
2A → B + C
First trial ;
[A] = x , Rate of the reaction = R
Rate law of the reaction can be written as:
..[1]
Second trial ;
[A] = 3x , Rate of the reaction = R' = 9R
Rate law of the reaction can be written as:
..[2]
[1] ÷ [2]
a = 2
Rate of the reaction :
The order of the reaction is 2. This is because in the rate law expression the the power of the concentration of reactant A id 2.
Sulfur dioxide is an example of air pollution.
It is the main component of acid rain. It is released into the air as a result of the burning of fossil fuels.
